Hydraulic CNC Electro-Hydraulic Synchro (2-WE67K-250x5000)

of machine is composed of tank, worktable, left and right housings and RAM. So it has high strength and good rigidity. Also it takes vibration to eliminate Stress. 2 Synchronization working principal of both machines: Adopting electric-hydraulic Proportional valve to ensure the synchronization of both machines. The proportional valve is made by BOSCH company with very good performance such as small friction between mechanic action pairs, fine electronic amplifier and electric magnet with high controlling force and continuous action. There are two raster displayers on both sides of machine to inspect the position of RAM continuously and feed back the signal to control system, then the control system will control electric-hydraulic valve to make two cylinders synchronization on one machine. Because the raster displayers are installed to "C" plates, not on housing plates directly, the deflection of RAM and frame when working will not effect its measuring and controlling precision. When two machines working together, the differential potentiometer installed between two machines will transfer the mechanic synchronizing signal into electronic one and feed back to synchronization plate and control system.
